Thank you Sir for your kind response.In mdout file :--------------- GPU PEER TO PEER INFO -----------------
|
| Peer to Peer support: DISABLED
|
| (Selected GPUs cannot communicate over P2P)
|
|--------------------------------------------------------
How can I enable Peer to Peer support??
Thanks and Regards,Saikat

It's 2. According to your output CUDA_VISIBLE_DEVICES is set to "0,1",
and there are 2 CUDA capable devices detected. Right now 3 tasks are
running on one GPU and 3 on the other, which is almost certainly not
what you want. You may get some speedup running across 2 GPUs if
peer-to-peer support is enabled, but you should benchmark. More useful
info on running on multiple GPUs can be found here:
